The shutdown pin lets a microcontroller or GPIO hold the amp in zero-current standby; a depop circuit suppresses the turn-on thump that otherwise sends a DC transient into the headphones.","metaTitle":"MAX4409ETP+ Class AB Stereo Headphone Amp, 80mW, DirectDrive","metaDescription":"Analog Devices MAX4409ETP+ Class AB stereo headphone amplifier, 80mW x 2 into 16Ω, DirectDrive, 20-TQFN.
